how to make a rom like what is in this pic by hacking

[ouso1999]

MMC1 is the hardware on the cartridge, I'm not sure what you mean.

so can i do that with softwares without hardwares?

No, for some games you will _need_ the right hardware, unless you rewrote the entire game.

u say some games not all.who makes multi cart,must need softwares.so what are the required softwares?
and if it is impossible to do that without MMC1 , then can anyone volunteer and do it 4 me?
u should know that i need to play it on PC not on famicom itself.

i'll be grateful for the person who'll help me with that and thank u all 4 help.[/b]

The softare is the games and the menu. Most games you'll only be able to put on a multi-cart though would be NROM, which requires no hardware. You were already linked to such a program.

I think the problem is that your posts are a bit hard to comprehend (possibly using online machine translation?) and people thought that you want to make a physical cart instead of a ROM file playable with a PC emulator (unless I also got it wrong).

Physical Famicom/NES carts all have some hardware in them (the only difference is how complicated the hardware involved is, which depends on the mapper used), but if you only need a ROM file playable with an emulator you don't need to build the hardware as the emulators emulate the mappers in software.

I think depending on the games, it may not be that hard to build a multicart ROM file (as people have already pointed you to some of the required resources), but still you need some basic knowledge on how stuff work.

I cannot understand though, if you only want the games to be playable with emulators, why bother making a multicart ROM? Instead, just load whichever game you want to play from the emulators (of if you feel that the interface of an emulator is not good enough, just use a frontend GUI).

P.S. Actually I couldn't see the image in the first post due to IMGSHACK's recent policy (images will only show up in external sites if either 1) the site is registered in their database or 2) the viewer has an IMGSHACK account) as I don't have an IMGSHACK account, so I'm just guessing what this is all about. Thus, I can be completely wrong...

yeah,u got it.that is exactly what i mean.sorry guys,it's my fault.i had to be clear at first.I mean i wanna play it with an emulator on pc.i'm so sorry.

i know , but i wanna make multirom looking like a cart of mine which i missed veryyyyyyy much , instead of dumping it 'cause i don't have a copynes and hard 4 me to buy.i wish you understood me.
so plz ,guys give me the required programs and some explanation how nto do that.

could u give me the names of the required programs , plz?
u should know that i wanna play it with the emulator.

i'm waiting 4 response

could u give me the names of the required programs , plz

As was mentioned earlier, No-Carrier has a program available here.


If you want to change the look of the menu, expand the number of games on the cart, or use non-NROM games, then I'm afraid you're going to have to learn a lot more about NES development before you attempt a project like this.

so what now?
i've downloaded it and that is the extracted folder



i can't open these files.what should i do then?

waiting 4 solution

[3gengames]

Read the ReadMe? I hope it'd explain how it works.

[ouso1999]

i can't find YY-CHR Program in English.all are in Japanese.
can anyone upload it 4 me?and if there is a topic explaining how to use these softwares to make multirom,plz refer me to it.
i'm sorry i know i'm tiring.

the read me text is telling me the usage not how to do that , so if there is a topic explaining how to use these softwares to make multirom,plz refer me to it.

[ouso1999]

what about rom larger than 40kb in PRG and CHR?and is there a program which can carry size of rom up to 3MB?

[3gengames]

No, those games will probably need a mapper that is either different [You'd have to hack it in software to play it, difficult sometimes, and sometimes impossible.] or need the whole ROM, even if the mapper is the same. [Can't fit a menu or full game in there.]

The only games that can be put on the cart are games with no mapper.

[tokumaru]

ouso1999, in case you don't know, NES games larger than 40KB (32KB PRG + 8KB CHR) need special hardware on the cart. These are called "mappers", and there are lots of them. When pirates make multicarts they often take games that use the same mapper and glue them together using a "master mapper". When they want to join games that use different mappers, they hack the games so that they can work with a different mapper. This is possible only if the new mapper can do everything that the original one could, otherwise there is no way for a less capable mapper to replace a more capable one.

Hacking games like this is no trivial task, and you will not be able to do it unless you have good knowledge of NES programming. There is no program that will easily allow you to do this with just a few clicks.

Edit: Ah forget it. It has already been brought up.

ouso1999: This is not something you will learn to do in a day. This is something you will probably have to dedicate months of your life to. You will have to learn the 6502 instruction set. You will have to spends days hacking and tracing each game's code.

As Gilbert said, the average person would just use an emulator and separate roms to run different games. We're not emotionally attached to the look and feel of your old multicart, so even if someone here COULD do it, they probably wouldn't just to make you happy because it would be a LOT of work. There are no tools available, because the result would be a worse way to do what is already possible with emulators and roms. No one will do this for you.

If you have Windows Vista or Windows 7, try nemulator, an NES emulator whose ROM selector looks like Wii Menu on steroids.

There is an English version in the official YY-CHR page, which is possibly a few versions older than the Japanese one (I think the recent .NET version is Japanese only at the moment).

Edit: Just checked the .NET version and found that it's mostly in ENglish.

I know ,so i ask u all to refer me to a topic teach me how to do that or even give the basics
